- Emissive display systems of the type of information, indication or indicator-button panels often display messages that only partially occupy their surfaces, whereas their backlighting systems generally provide uniform illumination over the entire area. surface, including parts out of messages. Unnecessary lighting of these parts is a pure electrical loss to the system and therefore adversely affects the performance of the backlighting system.

- a waveguide composed of a transparent or translucent substrate and at least two reflection zones with different reflection functions, on the back of the substrate,
- a light source adapted to illuminate the waveguide laterally.
- the light rays emitted propagate inside the substrate to the reflection zones. According to their reflection functions, these zones reflect a variable part of these light rays, outside the substrate, forming lighting zones on the face of the guide.
- the lighting device when the light source is off, the lighting device has no illuminated area.
- the characteristic of the light source is modulated so that this characteristic corresponds to the strong reflection capacity of these zones and the very low reflection capacity of the other zones.
- the device as briefly described above comprises at least one reflector, placed on the back of the substrate, after the reflection zones and on the edges of the substrate.
- the device as briefly described above comprises at least one reflector placed on the face outside the lighting zones.
- the device optimizes the performance by returning in the guide all the rays escaped from the guide, outside the lighting zones.
- the device as briefly described above comprises at least one transmissive optical filter, placed on the face of the substrate superimposed on the display areas.
- At least one transmissive optical filter partially covers a lighting zone, so that the illumination intensity inside the lighting zone can be varied.
- the device can refine the intensities of the lighting zones totally or partially, depending on the nature and shape of the transmissive filter.
- the reflection zones and the transmissive optical filters consist of an ink deposited directly on the substrate.
- the reflection zones and the optical filters of the device can be easily manufactured by printing means. According to particular characteristics, the reflection zones and the transmissive optical filters are produced by deposition of organic thin layers on the substrate.
- the reflection zones and the transmissive optical filters are produced by geographical shapes on the substrate.
- the modulation means is adapted to vary the light spectral band that reaches said reflection zones, said reflection zones having different spectral reflection bands.
- the modulation means when the modulation means varies the spectral band of the light rays that reach the reflection zones, they take different visual appearances, forming colored lighting zones and varied intensity.
- the modulation means is adapted to make varying a main polarization axis of the light rays reaching said reflection zones, said reflection zones having different reflections along the polarization axes.
- the present invention aims at a lighting device which comprises:
- a source of light adapted to frontally illuminate the support, the rays reflected by the reflection zones forming illumination zones on the medium of varied intensity.
- the direct lighting of the reflection zones is used to form lighting zones on the surface of any support.
- certain zones are made visible and other zones on the surface of the support are visible.
- the present invention relates to a lighting device which comprises: a front face containing at least one message to be displayed,
- a waveguide composed of a transparent or translucent substrate and containing at least one reflection zone on the back of the substrate, the reflection zone having the same shape as the message of said front face,
- a light source adapted to illuminate the waveguide laterally.

- the device proposes only lighting zones corresponding to the message to be displayed, partially covering the waveguide, and thus optimizes the electrical efficiency of the device.
- the message illuminated and displayed on the device is characterized better contrast, as a result of a darker message background in an unlit area.
- the present invention also relates to an electronic device having at least one of the following functions: a personal digital assistant, an organizer, a telephone, a game console, a laptop, an Internet access terminal, an ATM machine, a dashboard, a watch, a remote control, a walkman, a positioning system, an audiovisual signal receiver, an electronic, office or leisure equipment, a fax machine, a photocopier, a scanner, a reader of recorded media, a home automation system, household appliance, medical equipment, measuring device, analysis automat, automotive equipment, indication panel, switch, game device, decorative element, lamp, an electric button, a display panel, an electronic device comprising a lighting device as briefly described above.
